Fiber web production line and winder arrangement

Fiber web manufacturing line, which has at least two roller cutters respectively having an unwinding station (21A, 21B) and a slitting and winding section (26A, 26B), characterized in that the roller cutters of the production line are arranged successively in the machine line substantially that are their unwinding stations (21A, 21B) at the machine level (M) and the slitting and winding section (26A; 26B) of at least one on a level (N) below the machine level (M), and that (between the unwinding stations 21A , 21B) are arranged in the roller cutter return rails (41) of reel spools (13) which as a bearing (for the reel spools 13) and serve as an unloading point of machine rolls and / or the lower ends of machine reels.
